Step-by-step explanation:
Yes, an external microphone connected through the headphone jack of a phone can deliver quality recordings for acoustic instruments. While the built-in microphones on most phones may not capture the full detail and richness of acoustic instruments, an external microphone can greatly enhance the quality of the recordings.
An external microphone can provide better sound isolation, allowing for clearer and more accurate recordings. It can also offer different polar patterns, such as cardioid or condenser, which can help capture the nuances and dynamics of various acoustic instruments.
For example, a cardioid microphone can focus on the sound source and minimize background noise, while a condenser microphone can capture a wider frequency range and reproduce the subtle nuances of the instrument.
